I am second to none in my appreciation of female breasts, but if / where women are topless or their nipples are exposed, I consider that my problem not to trip over my tongue or stare impolitely.
I think it is worthwhile perspective to realize that men's nipples were considered improper to display in New York until 1937 (thus all those manly men in bathing suits with tops from the 20s).
If a situation is appropriate for a man to be wandering around without his shirt, it seems appropriate that a woman should have the same option.

The Fight to Free the Nipple
An outdoor book club in Brooklyn garners stares and glares in its literal support of the Free the Nipple movement.
In reading this story to my wife I said, "… They are part of a larger nipple…" That was supposed to be "larger movement".
Haha Freudian slip or purposeful?
